DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS

Definitions

As used in this description and the accompanying claims, the following terms shall have the meanings indicated, unless the context otherwise requires:

“Chat” means asynchronous interactive digital communication between two endpoints using at least one of text, video, voice, audio, and data files.

“Availability status data” means whether a chat channel has been opened for the business and optionally a rating of the responsiveness of the business, and optionally taking into account business rules established by the business. Availability status data may indicate status options including at least a plurality of the following: “away”, “off”, “busy”, “online”, and “open to receive messages even though not available for immediate chat”. Two parties to chat need not necessarily be online simultaneously in order for a chat channel to be opened for the parties.

A “user” is an individual who has an account with a system in accordance with an embodiment hereof for managing chat.

A “business user” is a “user” as defined herein who is registered as a user affiliated with a “claimed business”.

A “claimed business” is a business that has at least one “business user”.

A “chat channel” is a communication path between a user and a seat in a business selected by the user for engaging in chat. Each claimed business has at least one chat channel, and a claimed business may define a plurality of channels, wherein each channel can be assigned to a category of communication with the business. Moreover, each channel can be provided with a label that is visible to a user, so that the user can select a desired channel of the claimed business over which to engage in chat.

A “chat session” is a specific connection between at least one user who has been subscribed to a chat channel and at least one seat operator of the claimed business.

A “set” includes at least one member.

A “seat” is a chat node that can be staffed by an individual or robot (sometimes herein called an “installed application”) representing a given business in chat. Accordingly, when a user seeks to chat with a business having a plurality of seats, it is possible for the chat management server to subscribe the user to chat with a seat of the business that is not currently engaged in chat (or which currently has sufficient capacity to engage in chat) with the user (assuming of course that the seat is being occupied by an individual representing the business in chat).

A seat is “busy” if the number of concurrent chat sessions associated with the seat reaches a pre-specified threshold.

A “seat operator” is an individual or robot occupying a seat and representing the claimed business.

A “chat host” is an individual or group for which there has been established a personal account to host chat and for which there is at least one assigned seat.

A “computer process” is the performance of a described function in a computer using computer hardware (such as a processor, field-programmable gate array or other electronic combinatorial logic, or similar device), which may be operating under control of software or firmware or a combination of any of these or operating outside control of any of the foregoing. All or part of the described function may be performed by active or passive electronic components, such as transistors or resistors. In using the term “computer process” we do not necessarily require a schedulable entity, or operation of a computer program or a part thereof, although, in some embodiments, a computer process may be implemented by such a schedulable entity, or operation of a computer program or a part thereof. Furthermore, unless the context otherwise requires, a “process” may be implemented using more than one processor or more than one (single- or multi-processor) computer.

A “user device” is a computer that is used by a user and implemented as a desktop unit, a laptop unit, a tablet, a smartphone, or as any other computer having access to a network.

A “search signal” is a signal originating from a user device to indicate that the user device is running a process configured to support a chat session managed in accordance with embodiments described herein and it includes data characterizing criteria for a business with which the user seeks to chat.

When a device of a particular user is “logged in”, the device is authorized by the chat management server to send communications from, and receive communications to, the particular user.

An “installed application” is an application, provided by a claimed business, that is configured to run, under conditions established by the business, after a user has been subscribed to a chat channel in order to provide to provide communication functionality, between the business and the user, that is enhanced in comparison to simple chat. The application may be stored on the chat management server or on a server of the business.

“Business administrator” is a role assigned to a business user affiliated with a claimed business in which the business user is empowered by the chat management server to configure chat management settings pertinent to the claimed business.

“Location administrator” is a role assigned to a business user affiliated with a claimed business, as to a specific location of the claimed business, in which the business user is empowered by the chat management server to configure chat management settings pertinent to the claimed business solely with respect to the specific location.

“Business operator” is a role assigned to a business user affiliated with a claimed business in which the business user is not empowered by the chat management server to configure chat management settings for any other business user.

“Chat metadata” is data characterizing chat activity on the chat management server other than the specific content of the chat itself.

“RESTful” a set of architectural principles that govern operation of an application programming interface (API) for the chat management server described herein. These principles define structures that pertain to communication between clients and servers and are applicable, among other things, to how resource states are addressed and transferred over HTTP by a wide range of clients written in different languages.

FIG. 1 is a block diagram of processes implemented to subscribe a user to a chat channel with a business in accordance with an embodiment of the present invention. The processes are carried out on a chat management server. In process 11, the server receives a search signal over a first network from a device, under control of the user, to indicate that the user device is running a process configured to support a managed chat session. The search signal includes data characterizing criteria for a business with which the user seeks to chat.

In process 12 of FIG. 1, responsive to the search signal, the server identifies a set of businesses meeting the criteria, and for each business in the set of businesses, the server determines availability status data for each location. In process 13, the server transmits, to the device, availability status data for the set of businesses for display on the user's device. In process 14 of FIG. 1, the server receives over the first network a request message originated by the user on the device to enter a chat channel established for a selected one of the set of businesses. In process 15, responsive to the request message, the server subscribes the user device to the chat channel for the selected one of the set of businesses, and in process 16, the server transmits to the device, over the first network, a launch-chat command.

As we show in further detail below, although the processes have been described in connection with a single business with which the user of the device wishes to chat, embodiments herein support chatting of the user with a plurality of businesses. Also, although the processes have been described in connection with a single user device, embodiments herein support making chat history, and further chat, available to the user simultaneously on a plurality of devices. Of course, the processes illustrated with respect to a given user can be replicated with any number of other users who would use their own devices for engaging in chat with businesses of their own selection.

FIG. 2 is a schematic representation of event-driven architecture as implemented in embodiments of the present invention to provide asynchronous communication in chat sessions. Item 21 is a typical device of a user that makes a message post to the chat management server 22. The device 21 is subscribed to the same chat channel as the devices 23, 24, and 25 of other users. On receiving the message post from device 21, the server notifies the other devices subscribed to the same chat channel of the message, and so sends the notification to devices 23, 24, and 25. The event-driven architecture employed herein has the benefit of simplicity and scalability, while eliminate needless traffic associated with polling and other techniques used in the absence of event-driven architecture.

FIG. 3 is a block diagram of processes implemented in accordance with an embodiment of the present invention to assign a user device to a chat channel for a selected business and seat type. In process 31, the server receives a request message from a user device to enter a chat channel for a selected business and seat type. Before we explain the type of a seat, we point out that a business can engage a plurality of individuals to engage in chat with users. Each individual or robot allocated by the business to engage in chat occupies what we here call a “seat”. A seat, more particularly, is a chat node that can be staffed by an individual or a robot representing the business in chat. Accordingly, when a user seeks to chat with a business having a plurality of seats, it is possible for the chat management server to subscribe the user to chat with a seat of the business that is not currently engaged in chat (or which currently has sufficient capacity to engage in chat) with the user (assuming of course that the seat is being occupied by an individual representing the business in chat).

In various embodiments of the present invention, when a user seeks to enter into chat with a business, the business may itself have established a structure for handling chat of various different types. For example, the business may assign one set of seats to handling chat relating to product returns, another set of seats to handling technical questions concerning product usage, and another set of seats to handle order inquiries. Each set of seats is a different “type” of seat. Each different type of seat we call in this description and in the accompanying claims a “channel”. Embodiments of the present invention therefore accommodate a plurality of seat types (that is, a plurality of channels) that can be assigned and configured by the business (namely, by the “business administrator”) according to its own needs. Moreover, the user need not be presented with a monolithic icon representing the entire business for purposes of chat. Instead, the business may choose to have the user experience a different icon for each channel—in other words, the user may press one icon to chat with the business about a product return, another icon to chat with the business about technical questions concerning product usage, and yet another icon to chat with the business about an order inquiry. Moreover, when a user seeks to review chat history (discussed below, for example, in connection with FIG. 22), the chat history will reflect the user's chat experience for the channel (as opposed to simply chat with a given business operator), and the chat history will also show the name of the business operator in each chat session.

Returning now to FIG. 3, in process 31, the server receives a request message from a user device to enter a chat channel for a selected business and a seat type selected by the user. In process 32, responsive to the request message, the server determines the logical status for each seat operator, that is, determines whether an individual representing the business is currently occupying each seat. In process 33, the server determines physical availability status and device status for the user's device. In process 34, the server selects one operator from a list of available operators, using a suitable algorithm, such as round-robin or first-come-first served. If an operator is available, then in process 35, the server subscribes the user device to a chat channel for the selected business and the user.

FIG. 4 is a block diagram of processes implemented in accordance with an embodiment of the present invention to establish availability data for a business that can be used as part of availability data supplied to a user device. In process 41, the server receives a request message from a user device to determine availability for a selected business and seat type. The logical processes carried out by the chat management server have as a goal to notify the user if a selected business and seat type are available to engage in chat with the user. Accordingly, in process 42, responsive to the request message, the server determines if for the selected business and seat type there is at least one seat operator with status online. In process 43, the server compares seat capacity (maximum number of allowed chats per seat) and current number of opened chat channels for each seat, to determine if a new chat session can be created. In process 44, the server returns the status as available only if these criteria are satisfied. In various embodiments of the present invention, even if an operator is not currently available for the selected business, it may still be possible to subscribe the user to a chat channel, because in such a scenario the user's chat message can be forwarded to the business when an operator does become available. Whether the user is subscribed to a chat channel under such a condition, can be the subject of a configuration setting available to the business administrator.

FIG. 5 is a block diagram of processes implemented in accordance with an embodiment of the present invention to provide messaging services over various user devices. In process 51, the server receives a message in an active chat session from a device of a user who is engaged in chat in the chat session. In process 52, on receipt of the message, the server updates a cache of the active chat session; this cache stores on a current basis all messages in the chat. In process 53, the server determines what devices subscribed to the active chat session, other than the device issuing the message, are online. In process 54, the server sends the message directly to each online user device that is subscribed to this session (the devices having been identified in process 53) by syncing the user device with the active chat cache. In process 55, if any user has turned on forwarding, then the server forwards the message to any additional devices (determined by settings of the user) for which forwarded has been enabled by such user. In process 56, the server archives the message by storing it in the chat database.

FIG. 6 is a block diagram of processes implemented in accordance with an embodiment of the present invention to monitor and to manage chat sessions. In process 61, the chat process begins. At the server level, in process 62 (as explained in further detail in connection FIGS. 3 and 4), the chat management server receives the search signal, sends availability data, and subscribes the user device to an active chat session. In process 63, chatting begins. In process 64 (as explained further detail in connection with FIG. 5), each time a message is sent, the chat cache is updated and it is also synchronized with each online device that is subscribed to the chat session. Thus the process 64 is invoked when a user sends a message in process 68 or an operator sends a message in process 67. Similarly, process 64 is invoked every time there is a reconnection in process 616 following a disconnection as a result a connection problem in process 69 or connection closure in process 610 (each time identified by unsuccessful message delivery attempts by the server in process 615 or the passage of too much time to reconnect determined in process 617). If the time for reconnecting determined in process 617 has passed, the server will still attempt to perform forwarding in process 619 as discussed above, for example, in connection with process 55 of FIG. 5. The forwarding is performed for all devices specified in settings established by the user. Forwarding is attempted for all fallback devices in the order specified in accordance with processes 619, 620, and 621. If a duration has been established for expiration of the chat session, then in process 611 a session timer is checked to determine in process 614 whether the session has expired. In the event that it has expired, then in process 621 the chat session is closed and all participants in the chat are notified by updating the chat cache (as described in connection with process 64) and syncing it one last time with all online devices. Process 621 is also invoked if in process 613 the chat session is closed by the user or in process 612 the chat session is closed by the operator.

FIG. 7 is a block diagram of processes implemented in accordance with an embodiment of the present invention to handle circumstances when a business is not available to engage in chat at the time when a user seeks a chat session. The process starts in item 71. In process 72, the server receives a search signal from the user device and sends availability data in response, all as described in connection with previous figures. We now address cases wherein the selected business in not available to engage at the time the user seeks to chat with the selected business. In one case, in process 73, the selected business is not a claimed business; in this case, the availability data already sent in process 72 has notified the user that the business is not available for chat. Nevertheless, the user may indicate interest in chatting with the business, in which the server receives and stores data indicating user interest in chat in process 77. This data can be used later in contacting the selected business.

In another case in FIG. 7, in process 74, the business is currently offline, and the availability data already sent in process 72 has notified the user that the business is currently offline. Depending on settings established by the business, the user may be given an opportunity to select between either having the user's device currently subscribed to a chat channel or being notified when the business has come back online, and in process 78, the server carries out processes consistent with the user's selection. Similarly, in another case, in process 75, the business is currently busy, and the availability data already sent in process 72 has notified the user that the business is currently busy. Depending on settings established by the business, the user may be given an opportunity to select between either having the user's device currently subscribed to a chat channel or being notified when the business has come back online, and in process 79, the server carries out processes consistent with the user's selection.

FIG. 8 is a block diagram of architecture of a system for managing user chat experiences with businesses in accordance with an embodiment of the present invention, showing in particular the communication interface with users and businesses. Item 810 is a common access layer for all user devices, and gateways to other systems. Through the access layer 810 all chat system features are exposed using an API interface that employs a RESTful architecture. Devices, such as desktop computer 81, which may for example, be an Apple MAC computer or a PC computer running Windows 7, laptop or tablet computer 82 or smartphone 83, connect through their web browser applications, using the HTTP protocol, to the web server 89, which in turn communicates with other components of the system through the API 810. Alternatively, the smartphone 83 may run a special application to communicate directly with the API 810. Chat messages can be alternatively delivered to a variety of electronic devices using different network protocols and appropriate gateways. Some examples are the SMS Gateway 85, Email Gateway 86, and Jabber Gateway 87. The Core Business Application 813 contains all business logic and manages communication with external systems (such as the items discussed previously in this paragraph) and internal subsystems (such as Search, discussed in connection with FIG. 9, and Chat, discussed in connection with FIG. 10 below). The Business Application 813 may be replicated across multiple servers (represented as items 811 and 812) to support redundancy and scalability.

FIG. 9 is a block diagram of architecture of a system for managing user chat experiences with businesses in accordance with an embodiment of the present invention, showing in particular the components implementing business search capability and storage of data relating to users, businesses, chat metadata, event logs, and other system information.
